概括
黄斑脱落显著恶化了用于视网膜脱落的联合法科维特利切除术后的折射结果. 较长的和弦α,表示固定损失,与近视转移相关,突出其在折射预测错误中的作用.
科学领域:
- 眼科医生 眼科 眼科
- 视网膜外科手术 视网膜外科手术
- 折射误差分析 折射误差分析
背景情况:
- 用于视网膜脱落的联合法科维特雷切除术可能因折射误差而复杂化.
- 准确的眼内透镜 (IOL) 功率计算对于最佳的视觉结果至关重要.
- 中心固定损失,以和弦α表示,可能会影响生物识别准确性.
研究的目的:
- 为了研究斑点状况和固定 (弦α) 对结合性形切除术后折射结果的影响.
- 为了评估黄斑脱落,和弦α长度和折射预测误差之间的相关性.
主要方法:
- 对305只眼睛进行了回顾性观察性研究,这些眼睛经历了化和玻璃切除术的结合.

Angle Closure Glaucoma: Treatment
1.2K
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Open Angle Glaucoma: Treatment
961
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
